Any garage can service and mot it just tell them weight and height lol... As for habitation check its a waste of money... If everything works its fine fridge cooling okay and no black soot on vent its fine... Nice blue flame on gas hob grill its fine... Ive had mktorhomes for over 15years and never done one yet...

Plenty of dealers aroind Taunton area if your really bothered but they like your money...

I service mine myself and just get mot garage to check brakes etx at mot... Cambelt is worth checking when last changed... Most are fiat based but mines a renault master 3.0dci lol..
